What are the key differences between the Audi A7 and the Audi A8?

I am considering purchasing a luxury sedan from Audi, but I am unsure about the differences between their A7 and A8 models. Can someone please provide a breakdown of the key differences between these two models in terms of performance, features, and pricing?

The biggest difference between the A7 and A8 is in their exterior design. The A7 is a sportier, more coupe-like sedan with a sleeker silhouette, while the A8 has a traditional sedan shape. Additionally, the A8 offers more interior room and a smoother ride, while the A7 prioritizes performance and handling.
